in s.

he yabove and other objects may be attained by constructing a rollerbea-ring adapted for barrel shaped or double tapered rollers andcomprising an inner race having an ,annularly concaved outer surface to'accommodate the rollers, a split outer race having a similar concave'dinner surface and a tapered outer surface, and an adjusting andretaining ring having -a tapered inner sur- `face for engagementtherewith, whereby the rollers' may be inserted and retained in thebearing as a unit.

A practical embodiment of the invention is illustrated in theaccompanying drawing, in whichf v Figure 1 is an end elevation of'aroller bearing embodying the invention;

Fig. 2, a longitudinal, sectional' ,view through the same; v V

Fig. 3, 'a longitudinal, sectional view through the inner race;

Fig. 4, a side elevation of the outer race;

Fig; 5, a longitudinal, sectional view through the adjusting andretaining ring;`

and

- 6, an elevation of one of the barrel shaped rollers.

Similar numerals of reference refer to similar parts throughout thedrawing.

The inner race `1 v the usulcentral bore 2 for thejreception of an axleor the like, :and lis provided with the peripheralcurved groove .3shaped to conform to the barrel shaped rollers 4, such as are shown inFigs. 2 and 6. 'i f The outer race 5" is formedA of spring steel and isprovided uponits inner surface with the eripheral groove 6corresponding' to the ape of the rollers 4 andis split,.pref erabl inthe form ofa V, as best shown at 7in ig."4; j

The peripheral surface of the outer race 5 is f rusto-conical, 'as shownat 8`, threads 9 beingprovided at the smaller end thereof lforengagement with theinternal threads 10 may be provided with -sai of theadjusting and retaining ring 11, the

kinner surface of Which* is tapered asindicated at v12, to correspondwith the-taper 8 upon Vthe outer race. In assembling the bearing, theouter race is placed around the inner race and a number of rollers areinserted between the racesA In order to insert the last few rollers, thesplit outer race isexpanded, and after all of the' rollers have beenplaced in thel bearing, the outer race is permitted to contract to itsnormal position, retaining the rollers in place between the inner andouter races.

. The adjusting and retaining ring A11 lis then placed in positionaround the v outer race, the threads 10 thereon engaging thev threads 9upon theouterrace and as said ring is tightened, the conical innersurface 12 thereof bearing against the conical outer surface 8 of theouterfrace, contracts the same upon the rollers; f

The outer race can thus be easily and quickly adjusted to the rollersand in case of wear,a slight turn of the ring 11 will properly adjustthe outer race 5 to` take ,up Aitor the wear. f

.It will be seen that when the hearing is assembled, the rollers willbe-self-contained and the whole vbearing held together as' a unit, theouter race retaining the rollers and being adjustable to accommodate therollers -by means of the adjusting and retaining ring.

' I claim y 1. A roller bearing including anl inner race having agrooved periphery extending across its entire width, a split'outer racehaving a' grooved inner surface and a tapered periph ery, rollersconforming to the grooves in vsaid races dan adjusting ringpprovidedwith a tapereadrace and threaded upon one end portion of the outer race.

2. A roller'bearing including an inner race havin a grooved peripheryextending across its entlre width, an outer raceprovided with 'jaVshap'ed slit and having a groovedl inner surface and la taperedperiphery, barrel lsha ed rollers conforming to the grooves in races andan adjusting ring provided with -a tapered inner surface surroundinginner surface surrounding vthe outer l alsy the outer' race and threadedupon one end.

portion of the outer race.

In testimony that I'claim the above,

have hereunto subscribed my name.
